MEANS FOR SUPPORTING UPHOLSTERY-SPRINGS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed August 22, 1903. Serial No. 170,467.

To all whom it may concern:

Be it known that I, GEORGE E. BIGELOW, a citizen of theUnited States, residing atWorces-' ter, in the county of Worcester and State of Massachusetts, have invented anew and useful Means for Su pporting Upholstery-Springs, of

which the following is a specification.

This invention relates to a construction for combining and supporting upholstery-springs which has been especially designed for use in couches, bedsteads, or for similar purposes.

The especial object of this invention is to combine the upholstery-springs and tie-wires with the sheet-metal supporting-strips so that the parts will be fastened together in a strong, simple, and eflicient way without the use of special fastening-clips or other additional material. I

To this end this invention consists of the parts and of the combinations of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figurel is a plan view of sufiicient parts of a springframework to illustrate the application of my invention thereto. Fig. 2 is an enlarged perspective view showing the manner in which a tie-wire and a fastening-coil of an upholsteryspring are inserted into the receiving-slots of a sheet-metal supporting-strip. Fig. 3 is a similar view showing the parts after the strip has been clenched to fasten the spring and tiewire in place, and Fig. 4 is a detail view illustrating a form of tool which may be employed for fastening the springs.

To fasten the springs in place which are employed in upholstering couches, bedsteads, or for similar purposes, it has heretofore usually been customary to provide special clips or binding-wires for fastening the, springs in place, or in some cases it has been the practice to thread the coils of the upholsteryspring through eyes in the supports therefor.

The especial object of this present invention isto provide for fastening the parts together in constructions of the class referred to in a simpler, more direct, and economical manner and at the same time to produce a more rigid and permanent structure. To accomplish this purpose, the springs are carried by sheetmetal supporting-strips, which are provided ith special-shaped slots or eyes for receiving one coil of each spring. Similar slots are also preferably provided for receiving and fastening the tie-wires.

Referring to the drawings and in detail, A

, designates the side bars of a framework. EX-

tending from end to end of the framework are the sheet-metal supporting-strips 10, which are provided with twisted ends turned at right angles to the body portions of the sheet-metal strips and fastened in place by screws 11. Extending transversely'through the supporting-strips 10 are one or more tie-wires 12. The springs 13 may be of any of the usual or ordinary constructions. In the present instance I have illustrated the ordinary singlecone upholstery-spring, although it is to be understood that my invention is equally applicable to the hour-glass or double-cone springs, if desired.

The way in which the parts are secured together in a construction embodying my invenvention is most clearly illustrated in Figs. 2 and 3. As shown in Fig. 2, each of the sheetmetal supporting-strips 10 is provided near its upper edge with specially-shaped slots for receiving the coils of the springs and for receiving the tie-wires. A slot for receiving the coil of a spring is preferably provided at its end, with pinching sections or recesses 14, which are separated by a depression 15. As shown in Fig. 3,the attaching-coil of the spring 13 may be inserted laterally through the slot therefor and is then fastened in place by driving down the strip of material 17, which forms the upper side of the slot. This may be done by a tool T, which, as illustrated in Fig. 4, may be slotted at its lower end or provided with guide-legs 6, so that the tool may straddle the sheet-metal strip 10 and may then be hammered to drive down the strip 17 into the socket below thesame. By doing this I have found in practice that a firmly-gripped connection may be made with the attaching-coil of each spring and that the parts may be as sembled in this way without the use of special fastening-clips or binding-wires, while at the same time a stronger and more rigid construction will be produced. The tie-wires 12 may be locked to the supporting-strips in similar ways. For example, as shown in Fig. 2, the strip 10 is provided with a somewhat shorter slot having the locking-notch 18 at its end and a central depression into which the strip of metal 20 above the slot may be hammered or bent down. In setting or fastening the tiewires 12 special tools are not required, an ordinary hammer being used for this purpose, if desired.

I am aware that changes may be made in practicing my invention by those who are skilled in the art without departing from the scope thereof as expressed in the claims." "I

do not wish, therefore, to be limited to the constructions I have herein shown and described, but

What I do claim, and desire to secure by Letters Patent of the United States, is

1. In a construction of the class described, the combination of a sheet-metal supportingstrip and an upholstery-spring, said supporting-strip having a slot with tapering pinching sections at its ends for receiving the attachingcoil of the spring and located near the edge of the supporting-stri p so that the material above the slot may be bent in to fasten the parts together.

2. In a construction of the class described, the combination of a supporting-strip and an upholstery-spring, the supporting-strip being provided with a slot for receiving the attaching-coil of the upholstery-spring, which slot has tapering pinching-sections at its end with a depression between them and said slot being located near the edge of the strip so that the material abovethe same may be bent down into the depression to fasten the parts together.

3. In a construction of the class described, the combination of a frame, sheet-metal supporting-strips extending across the frame, a tie-wire extending transversely through the supporting-strips, and a plurality of upholstery-springs, the supporting-strips being provided with slots for receiving the attachingcoils of the upholstery-springs, each of said slots having narrow recesses at its ends separated by a central depression and said slots being located near the edges of the strips, Whereby the material above the same may be bent down to lock the parts together.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE E. BIGELOW.
